Документ Вимушені коливання циклосиметричного лопаткового апарату з випадковим технологічним розладом(НТУ "ХПІ", 2007) Жовдак, В. О.; Ларін, Олексій Олександрович; Головко, О. М.Investigation of the harmonic vibration of the lump-mass discrete cyclic model of bladed disk of the first stage of the stem turbine with the random mistuning is carried out by means of Monte-Carlo method. Various realizations of the mistuning and corresponding to them amplitude-frequency characteristics are investigated. The expectations and variances for the frequency-response curve are built.Документ Активное гашение нестационарных колебаний прямоугольной пластины(НТУ "ХПИ", 2007) Янютин, Е. Г.; Воропай, Алексей ВалериевичThe procedure of active damping of the nonstationary vibration for rectangular plate is presented. The damping is executed by the system of four nonstationary concentrated forces obtained as a result of solving an inverse problem of Timoshenko's plate dynamic theory. The problem is reduced to the system of the first-kind Volterra integral equations solved numerically with means of Tikhonov's regularization method.Документ К вопросу о тестовых задачах для кругового цилиндра(НТУ "ХПИ", 2007) Ткачук, Николай НиколаевичJn the paper the construction of a series of master solutions for circular cylinder is discussed. These solutions were applied to verify a finite element model with two cases of boundary loading.Документ Определение точности метода фотоупругости(НТУ "ХПИ", 2007) Тесленко, А. А.New method of accuracy definition for the method of photoelasticity is considered in the paper. Essence of a method consists in the modelling way of accuracy determination. Accuracy is determined in comparison of initial (modelling) stresses and stresses determined in the simulated way of measurement. The stresses determined in real experiment are used as initial (modelling) stresses. The correctness of this method is investigated.Документ Про одну умовно потенціальну силову схему(НТУ "ХПІ", 2007) Таран, С. Н.The specific force scheme determined in bounded area is considered in this work. The introductions of a potential for the movements in the strictly certain direction is supposed in this scheme.Документ Напряженно-деформированное состояние зубчатых передач с позиций термоконтактного деформирования в упруго-пластической области и в условиях ползучести(НТу "ХПИ", 2007) Приймаков, А. Г.; Устиненко, Александр Витальевич; Приймаков, Григорий АлександровичContact task in a resiliently-plastic area at presence of chafing in the contact area is considered. The method of determination of thermal-contact strains and stress of some stratum, being under the surface stratum of tooth in the conditions of creep is offered.Документ Оптимальное проектирование механизма наклона плавильной печи: модели для анализа напряженно-деформированного состояния(НТУ "ХПИ", 2007) Полищук, Тарас ВикторовичIn this paper models for research of stressedly-deformed state of model of smelting furnace are described. The generation of geometry and finite-element net is conducted with integrated parameterization of dimensions, efforts and parameters of finite-element net.Документ Изменение теплопроводности контакта элементов лазерного гироскопа под действием прижимного усилия(НТУ "ХПИ", 2007) Погорелов, Сергей Юрьевич; Счастливец, Кирилл Юрьевич; Марусенко, Светлана ИвановнаThe measurement accuracy of ring laser gyros depends on temperature field parameters. In the proposed paper the influence of contact thermal conduction between the construction cover and laser gyroscope resonator including deformations depending on mechanical construction spring pretension was analyzed.Документ Расчет посадок с натягом при овальности и эксцентриситете соединяемых деталей на основе ПК ANSYS(НТУ "ХПИ", 2007) Перин, А. П.; Андреев, Арнольд ГеоргиевичIn this paper the mode of deformations of interference fit of bush and shaft in various ways of fitting was analyzed, namely round shaft and round aperture of the bush, oval shaft and round aperture of the bush, round shaft and bush with eccentricity, oval shaft and bush with eccentricity and the angel 0, 45 or 90 degrees between out-of-roundness and eccentricity. Hertzian problem is solved by the program complex ANSYS. Results are given in the form of tables and drawings.Документ Переходные и стационарные режимы в системе с ограниченным возбуждением(НТУ "ХПИ", 2007) Перепелкин, Николай Викторович; Михлин, Юрий ВладимировичTransient in a non-ideal system with limited excitation, where an interaction of engine and linear elastic subsystem takes place, is considered. The transient in described by the multiple scales method. Possibility of transfer to stationary regimes, including a resonance regime, is considered. Numerical simulation confirms an efficiency of the obtained analytical solutions.
